A kind of bridge anticollision laser level detection method
Technical field
The present invention relates to bridge safety supervision field, especially a kind of bridge anticollision laser level detection method.
Background technique
Current bridge anticollision detection is usually the anticollision height in bridge (ship can pass through the maximum height at bridge bottom)
Place installation laser transceiver, laser transceiver relative to water surface level project laser, with this come detect ship whether superelevation, tool
The advantages that some costs are low, easy to detect, it is only necessary to which the laser for guaranteeing laser transceiver during installation is horizontal project;But
Due to extraneous factor etc. (such as blowing and raining), can laser transceiver be shaken often, laser transceiver occurs inclined
It moves, so that the laser that laser transceiver projects is projected without respect to water surface level, eventually leads to laser transceiver and report by mistake
The case where failing to report leads to the generation of accident.
In order to ensure laser transceiver is not in that wrong report is failed to report, need periodically to laser transceiver carry out level detection,
Whether the laser for judging laser transceiver transmitting is horizontal injection, and currently used method is to lease ship in locality, then
Aboard ship install with the anticollision target with equally height of bridge, when ship on the water when driving, if laser transceiver not according to
Be mapped to target center, illustrate that laser transceiver is deviated, then corrected, it is on the contrary then without correct, this detection
The higher cost that method expends, and there are many uncertain factors, such as lease causes to detect whenever and wherever possible less than ship
Laser transceiver, it is inconvenient for operation.
Summary of the invention
For overcome the deficiencies in the prior art, the present invention provides a kind of bridge anticollision laser that consuming is low, easy to operate
Level detection method.
The technical solution adopted by the present invention to solve the technical problems is:
A kind of bridge anticollision laser level detection method, this method are realized by total station and unmanned plane to being mounted on bridge
Laser transceiver carries out horizontal detection, is provided with target on the unmanned plane, its step are as follows:
1, total station is placed on embankment, adjusting total station makes it form visual horizontal line on the water surface.
2, using laser transceiver described in total station observation, the difference in height between laser transceiver and visual horizontal line is obtained
For H.
3, by unmanned plane described in the total station observation, the effective range for making unmanned plane hovering work in laser transceiver
The interior position for being H apart from visual horizontal line difference in height.
4, target is observed by the eyepiece of laser transceiver, adjusts to the foresight center of eyepiece and is overlapped so with the target center of target
After fix.
Further, in the step 1, the total station is placed between the laser transceiver and unmanned plane.
Further, the laser transceiver is mounted at the anticollision height of bridge.
The beneficial effects of the present invention are: the present invention realizes the level inspection to laser transceiver using total station and unmanned plane
It surveys and corrects, easy to operate and consuming is low, and is not influenced by extraneous factor, can detect whenever and wherever possible, improve the convenience of detection
Property.
Detailed description of the invention
Present invention will be further explained below with reference to the attached drawings and examples.
Fig. 1 is structural schematic diagram of the invention.
Specific embodiment
Referring to Fig.1, a kind of bridge anticollision laser level detection method, this method are realized by total station 1 and unmanned plane 2
3 carry out level detection of laser transceiver to being mounted on bridge, is provided with target 4 on the unmanned plane 2, its step are as follows:
(1), total station 1 is placed on embankment, adjusting total station 1 makes it form 5 (visual horizontal line of visual horizontal line on the water surface
Axis when for total station camera lens level).
(2), the laser transceiver 3 is observed using total station 1, obtained between laser transceiver 3 and visual horizontal line 5
Difference in height is that (total station can measure the company of the distance between total station and laser transceiver and laser transceiver and total station to H
The angle of line and visual horizontal line can be obtained by height H by trigonometric function calculating).
(3), the unmanned plane 2 is observed by the total station 1, there is the hovering of unmanned plane 2 in what laser transceiver 3 worked
Imitate the position for being H apart from 5 difference in height of visual horizontal line in range.
(4), target 4 is observed by the eyepiece of laser transceiver 3, adjusts the target center weight to the foresight center of eyepiece and target
It closes then fixed.
In the present embodiment, in order to allow total station 1 more easily to observe laser transceiver 3 and unmanned plane 2, it may be preferable that by institute
Stating middle position that total station 1 is placed on the laser transceiver 3 and unmanned plane 2 or general middle position, (i.e. middle position is attached
Close position);In the present embodiment, the unmanned plane 2 is preferentially hovered in the effective range that the laser transceiver 3 works just
Front, during the foresight center for adjusting eyepiece is overlapped with the target center of the target 4, without being carried out to laser transceiver 3
It significantly rotates, facilitates adjusting.
In the present embodiment, the laser transceiver 3 is mounted at the anticollision height of bridge, is received by the above method to laser
Hair device 3 carry out horizontal detection and correct after, laser transceiver 3 can accurately detect traveling ship whether superelevation, avoid out
The case where now reporting by mistake and fail to report, to provide reliable guarantee with traffic safety waterborne on bridge.
Above embodiment cannot limit the protection scope of the invention, and the personnel of professional skill field are not departing from
In the case where the invention general idea, the impartial modification and variation done still fall within the range that the invention is covered
Within.
